To read the Northern Lights forecast as accurately as possible, it’s essential to understand several elements. First and foremost, you should look for the KP value (KP index). This value provides an indication of how wide the aurora oval is expected to be and, consequently, how far south the Northern Lights will be visible. The required KP value to observe the Northern Lights depends on the latitude of your location.
In this table, you can search for municipalities and regions throughout the Nordic countries (Norway, Denmark, Sweden, Finland, Iceland, the Faroe Islands, and Åland) to find out the KP value required to see the Northern Lights from the respective location. You can also find more information about the other elements in the Northern Lights forecast and their interrelationships here. Please note that the overview is based on information found online, and there may be errors.
